Parametric Horn Design

The principle barrier to more widespread use of numerical techniques for horn design is not a shortage of advanced computational libraries, rather the difficultly in defining the problem to solve in a suitable format. The traditional approach of creating horn geometry in large commercial CAD programs then exporting, meshing, assigning conditions, solving, and inspecting results denies the engineer the ability to easily iterate the design. We introduce an object-orientated parametric description of a horn that enables the engineer to modify meaningful parameters to generate geometry of appropriate complexity. The entire process is performed in one environment and an early implementation has been shown to allow nearly 100 iterations of one horn in one week. Results for this and another multi-driver HF horn are given.

The Engineering Briefs at this Convention were
selected on the basis of a submitted synopsis,
ensuring that they are of interest to AES members,
and are not overly commercial. These briefs have
been reproduced from the authors' advance
manuscripts, without editing, corrections, or
consideration by the Review Board. The AES takes no
responsibility for their contents. Paper copies are
not available, but any member can freely access
these briefs. Members are encouraged to provide
comments that enhance their usefulness.
